Type–C QPOs are strong (rms amplitude \(\sim \)  21 %), narrow (Q–factor \(\sim \)  4–12) with centroid frequency varying within 0.1\(-\) 15 Hz and superimposed on a strong flat-top noise [1]}, [2]}. As displayed in Fig. REF  and evident from the PDS fitting parameters listed in Table REF , the QPO frequency varies in the range 1.11 – 1.67 Hz, the Q-factor ranges within \(\sim \)  5–12 and a broad Lorentzian knee frequency is also present in our observations. This confirms that the observed low-frequency QPO to be of type–C. The PDS plots displayed in Fig. REF  also confirm the same type of low-frequency QPO. Both the PDS are Leahy-normalized and noise subtracted.
